Top Ten Overworld Themes in Pokémon Sun and Moon

Overworld counts as being the theme of specific locations, and not while battling or encountering certain characters.
The Top Ten
1 Ula'Ula Island

This theme sounds very happy, adventurous and nostalgic! It makes me feel like we're on an adventure.

2 Mount Lanakila
3 Tapu Ruins

This theme sounds so decrepit and ominous... it makes you feel like you shouldn't be here, just as it should.

4 Poni Island
5 Malie City (Day)
6 Hau'oli City (Day)
7 Vast Poni Canyon
8 Route 1
9 Akala Island
10 Mahalo Trail/Melemele Meadow
The Contenders
11 Po Town
12 Hau'oli City (Night)

Its got a relaxing jazz feel. One of few themes done on piano.
